Frequently Asked Questions
What locksmith services does Locksmith Guarantee offer in Gaithersburg, MD?
We provide a full range of locksmith services in Gaithersburg including home lockouts, lock installation and repair, rekeying, key duplication, car lockouts, transponder key programming, ignition repair, commercial lock systems, smart lock installation, master key systems, and electric strike installation.
What is a business rekey service and when is it needed?
A business rekey service changes the internal pin mechanism of your existing locks so they operate with a new key. Recommended when keys are lost or stolen, when an employee with key access leaves, or when you take over a new commercial property. It is reliableer and more affordable than full lock replacement.
Do I need to replace my locks to rekey them?
No. Rekeying only changes the internal pins inside the lock cylinder — the hardware itself stays in place. This makes rekeying significantly more cost-effective than replacing locks while achieving the same security benefit.
Can you rekey all locks to work with a single key?
Yes. We can rekey multiple locks across your Gaithersburg home or business to operate with one master key for convenience, while still maintaining individual key access for specific doors if needed.
Can rekeying improve my business's security?
Absolutely. Rekeying enhances security by invalidating all previously issued keys and ensuring only authorized individuals have access. It is the most efficient way to reset access control after a personnel change or security concern at your Gaithersburg business.
